My invention pertains to facing boards, such as are employed, for instance, for attachment to the lower side of a floor structure, to provide a ceiling for the space below the latter.

According to modern building practice, where structural steel floors, or floors of special fabricated metal, are employed, it has become usual to finish the lower sides of the floors, to produce ceilings, by means of facing boards suspended therefrom, and the attachment of such facing boards in a secure and satisfactory manner to the floor structure has required a considerable amount of time and labor. An instance of this occurs in the usual method of suspending the facing I boards by wiring them to the floor structure above. This involves that the workman shall hold or brace the facing board in a horizontal position beneath the floor structure and reach in, between the sides or ends of the board and the floor structure, to apply the wires between the two elements. The work is tedious and very timeconsuming.

It is the principal object of my present invention to provide a facing board which can be secured in place with exceptional ease and speed as compared with prior boards intended for the same or similar purposes.

By way of example, I have described in the following specification, a facing board constructed in accordance with my invention and shown the same as applied to a special form of metal flooring known as Keystone flooring. I wish it understood, however, that changes may be made in the construction of the facing board, and that it can be otherwise applied, without exceeding the scope of the invention, as defined in the appended claims.

In the drawing:

Fig. 1 is a perspective view of a portion of a metal floor of the type referred to, having my improved facing boards applied thereto, to constitute a ceiling;

Fig. 2 is a perspective view of a length of the facing board;

Fig. 3 is an enlarged section, taken on the line III-III of Fig. 1;

Fig. 4 is a further enlarged section, taken on the line IV-IV of Fig. 3;

Fig. 5 is a side View of Fig. 4; and

Fig. 6 is a detail view of a filler strip which may be employed.

Referring now particularly to Fig. 1, the metal flooring shown, known as Keystone flooring comprises a number of lower sections, welded or otherwise secured together, of metal stamped to form walls 10 inclined with respect to the vertical, and

horizontal walls 11 and 12. Upon these sections are superposed upper sections, 13, stamped to a channelled shape, the top of which may carry I concrete or the like, 14. Disposed between certain of the walls 10 of the lower sections are horizontal cross bolts 15. In applying facing boards to such floors, to constitute a ceiling for the room below, it has been customary to attach Wires between the facing boards and the cross bolts 15' in the manner above indicated.

The facing board of my invention comprises a layer'of wall board, which may be of the well known character which includes a body 16 of gypsum or the like enclosed between paper sheets 17, and a layer of plaster or the like 18. To the facing board there is applied a plurality (two are usually sufficient) of angle irons 19. These are secured to the wall board by means of bolts 20, whereafter the wall board being inverted, the plaster 18 is poured, leaving the nuts and the ends ofthe bolts imbedded in the plaster, thereby providing a finished plaster surface at all parts of the facing board that are exposed.

To the angle irons 19 is secured a series of spaced connectors 21 formed, at their upper ends, with hooked portions 22 adapted to engage over the cross bolts 15. The height of these connectors, which may be varied to suit the distance desired between the ceiling and the floor structure, is sufiicient so that the facing board can be pushed upward, as a whole, to allow the connectors to be hooked over the cross bolts and then be allowed to descend until it is supported upon the cross-bolts. The connectors maybe spaced at a. considerable distance apart while still being capable of supporting the facing board securely.

sides by the wall board. When the facing boards are in place, this leaves a channel in which a filling 23 of plaster (Fig. 3) can be applied to produce a continuous finished surface for the ceiling.

It is frequently desirable that the facing boards be merely suspended from the flooring in the manner shown, as this is entirely secure and at the same time vibrations of the building,which tend to produce cracking of the plaster,-are not communicated to the ceiling. When it is desired that the connection between the floor and ceiling be rigid against upward pressure as well as downward, inserts 24 which I provide for the purpose are interposed between the facing board and the bottom horizontal walls, 12, of the flooring, as shown in Fig. 3. These inserts are preferably channel shaped, to provide against the possibiilty of tipping.

It will be noted that the facing board of my invention is rigid, sturdy and economical to produce, and at the same time is exceptionally easy to apply on the job. All that is necessary is to raise it upward and hook it in place. It will be observed, further, that a ceiling composed. of the facing board of my invention has a finished plaster face, which may be readily sized if de-' sired, that can be painted immediately, or immediately covered with paper or other, decoration, requiring only the filling of the joints. Not only does this save the time that would be necessary to apply plaster by hand, on the job, but it obviates the time required for drying out plaster, which ordinarily postpones the time when a room or building is ready for occupancy.

I claim:

1. A facing board for attachment to building structure, said board comprising a base, layer, a support member mounted on said base layer, securing means passing through said base layer and said support member, a layer of cementitious material on the side of said base layer remote from said support member, thereby to cover said securing means at such side, and rigid members, fixedly associated with said supportmember, for connecting said facing board to the building structure.

2. A facing board for attachment to building structure, said board comprising a base layer, a support member mounted on said base layer, securing means passing through said base layer and said support member, a layer of cementitious material on the side of said base layer remote from said support member, thereby to cover said securing means at such side, and elongate hooks fixedly associated with said support member, adapted to engage portions of said building structure to connect the facing board thereto.

3. A facing board for attachment to building structure, said board comprising a base layer, a support member mounted on said base layer, securing means passing through said base layer and said support member, a layer of cementitious material on the side of said base layer remote from said support member, thereby to cover said securing means at such side, rigid members, fixedly associated with said support member, for connecting said facing board to the building structure, and a spacing member for insertion between said facing board and the structure.

4. A facing board for attachment to building structure, said board comprising a base layer, a support member mounted on said base layer, securing means passing through said base layer and said support member, a layer of cementitious material on the side of said base layer remote from said support member, thereby to cover said 1 securing means at such side, elongate hooks fixedly associated with said support member,

adapted to engage portions of said building structure to connect the facing board thereto, and a spacing member, of thickness substantially equal to the distance between said base layer and the building structure when said hooks are engaged with the latter, for maintaining said hooks firmly in such engagement.

5. The combination with a floor structure comprising a metallic channelled member having spaced abutments in channels thereof, of a facing board for attachment to said floor to constitute a ceiling, a support member rigidly secured to said facing board, and a plurality of hooks rigidly secured to said support member for engaging said abutments said hooks being spaced to accord with the spacing of said abutments, whereby said facingboard may be moved bodily to bring said hooks into engagement with said abutments to leave said facing board suspended from the latter.

6. The combination with building structure having a plurality of spaced abutments, of a facing board having rigidly secured to one side thereof a' plurality of outwardly extending rigid members, spaced to accord with the spacing of said abutments, for engagement with said abutments whereby said facing board may be moved bodily to bring said rigid members into engagement with said abutments to leave said facing board suspended from the latter.

'7. The combination with building structure having a plurality of spaced abutments, of a facing board for attachment to said structure, a stiffening bar secured to said facing board, and a plurality of rigid members rigidly secured to said stiffening bar and extending outwardly therefrom, said members being spaced to accord with the spacing of said abutments, whereby said facing board may be moved bodily to bring said rigid members into engagement with said abutnients to leave said facing board suspended from the latter.
